Jay-Z upped his net worth from $810 million to $900 million over the past year, seizing hip-hop’s cash crown for the first time since Forbes started counting back in 2011. The Brooklyn-born mogul’s jump is due mostly to the rising value of his interests in Armand de Brignac champagne and D’Ussé cognac, on top of nine-figure ownership stakes in his Roc Nation empire and Tidal streaming service. Dre ranks third with $770 million, creeping upward thanks to the market trends boosting his nine-figure windfall from Apple’s $3 billion buyout of Beats in 2014. (Forbes)
